How would that happen? The IRS has had a bounty out on it for years and it hasn't been collected. Once the new FCMP+ features are released, it will be completely untraceable. The only thing they can get on you now is an IP address if you use one of the public Chainalysis nodes. Running your own node is the best way to go anyway.
They can't stop Monero, they have tried, they have failed.
Yes, Monero is Proof of Work, the most decentralized form of POW actually because it can be mined on anything with a CPU. I mine it on 2 Macbooks and an old gaming PC.
Yes, Monero has multiple block explorers. I would suggest doing some research for yourself on the subject.
Good points.
Thanks for the information.
